Foursquare users have put a lot of energy into leaving tips and raves about locations on the geo-aware social app, but that doesn't help if you're not a member. FourWhere publicizes and organizes Foursquare's venues, "yelps" and tips/reviews for everybody's benefit.

FourWhere is really handy and a breeze to get started with—with one small catch. Search for the city you're exploring in the upper-right bar and confirm the location. Then you'll see, well, nothing. Right-click somewhere in the map that pops up, though, and you can choose to see all nearby venues that Foursquare users have checked into, only places with reviews/comments, or clear your map and start over in another area. Mouse over a blip on the map, and the user and comment that created it are instantly highlighted in the right-hand column.

If Foursquare users are going to spend all that time on their smartphones, getting all righteous about the absolute best cannoli in town, everybody should benefit, right? FourWhere is free to use, no Foursquare membership required.
